Benefits of technology
"The present invention is a table saw with an angle indicating device for accurately tilting the saw blade relative to the supporting base. This allows for easy and precise operation of the saw blade. The table saw includes a supporting base with a curved channel and a cradle pivotally attached to the supporting base with a pivot rod. There is also a bevel sector gear with a rack on the cradle and the arbor bracket, and a worm engaged with the rack on the bevel sector gear of the cradle for pivoting the bevel sector gear and the arbor bracket relative to the supporting base. The saw blade is rotatably attached to the arbor bracket with an axle, and a motor is attached to the saw blade for rotating it. A follower is engaged in the curved channel of the supporting base and a signal generating device is attached to the supporting base for detecting the bevel angle of the arbor bracket and the saw blade relative to the supporting base. The signal generating device includes magnetic members and the supporting base includes a scale with a graduated surface for indicating the angle. A control device is provided for receiving and processing the signal from the signal generating device to indicate the bevel angle of the arbor bracket and the saw blade relative to the supporting base."
Problems solved by technology
However, the typical woodworking machine has no angle indicating devices to indicate the tilting angle of the saw blade relative to the supporting base such that the user may not easily know the angular positions of the saw blade relative to the supporting base and such that the user may not easily and precisely operate the saw blade of the typical woodworking machine.
However, the angular positions of the saw blade relative to the supporting base may not be precisely read the user unless the user is precisely stood in front of the bevel pointer and the scale, and the angular positions of the saw blade relative to the supporting base may only be roughly estimated by reading the digit or graduation provided on the scale.
However, similarly, the typical table saws also have no angle indicating devices to indicate the tilting angle of the saw blade relative to the supporting base such that the user may not easily know the angular positions of the saw blade relative to the supporting base and such that the user may not easily and precisely operate the saw blade of the table saw.

Abstract
A table saw includes a curved channel formed in a supporting base, a cradle attached to the supporting base, an arbor bracket attached to the cradle for supporting a saw blade and a motor, a height shaft attached to the cradle and extended through the curved channel of the base for engaging with the arbor bracket, a tilt shaft attached to the base and engaged with the cradle for adjusting the saw blade relative to the base to selected angular positions, a follower slidably engaged in the curved channel of the base, and a signal generating device attached to the follower for detecting a bevel angle of the arbor bracket and the cradle and the saw blade relative to the base and for precisely showing the angle with digits.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a table saw or a woodworking machine, and more particularly to a table saw including an angle indicating device for precisely indicating the tilting angle of the saw blade relative to the supporting base and for allowing the user to easily and precisely operate the saw blade of the table saw.[0003]2. Description of the Prior Art[0004]Typical table saws comprise a saw blade rotatably supported in a supporting base, and a rotatable elevation wheel and a tilt wheel attached to the supporting base and coupled to the saw blade for adjusting the saw blade relative to the supporting base to any selected or predetermined angular positions in order to suitably cut or machine the work pieces.[0005]For example, U.S. Pat. No. 5,024,257 to Lloyd discloses one of the typical woodworking machines which also comprise a rotatable elevation wheel and a tilt wheel attached to the supporting base and couple...
